1 Claim.

The present invention relates to the art of home canning or preserving, and has for its primary object to provide, in a manner as hereinafter set forth, novel means for vacuum sealing Mason jars without the necessity of resorting to hot water baths, oven canning and other methods in widespread use at present.

Other objects of the invention are to provide a Mason jar sterilizing and sealing device of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing, and still further objects and advantages of the invention, will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a perspective view of a sealing device constructed in accordance with the present invention.

Figure 2 is a view in side elevation, showing the nozzle portion of the device in use.

Figure 3 is a top plan view, showing a, portion of the device in use.

Fi ure 4 is a View in longitudinal section through the portion of the device shown in Figure 3, taken substantially on the line 4-4 of Figure 3.

Figure 5 is a view in longitudinal section through the other end portion of the device.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a flexible steam conduit I of suitable length, diameter and material. Mounted on one end portion of the conduit I is a tube 2. Formed integrally with the tube 2 is a thin, flat, substantially wedge-shaped nozzle 3 having steam discharge openings 4 in its lower portion.

The tube 2 extends transversely through one end portion of an elongated, rigid handle 5. Also mounted on this end portion of the handle 5, adjacent the nozzle 3 and parallel thereto, is a thermometer 6. The thermometer 6 may be suitably marked or graduated, as at I.

Mounted on the other end of the flexible conduit I is a connector 8. The connector 8 includes a tapered, tubular plug 9 of wood or other suitable materialwhich is insertible in the steam discharge neck III of a teakettle II, for exam le. The connector 8 further includes a substantially cup-shaped shield or cap I2. The shield I2 is for the reception of the steam neck III of the kettle I I.

In the embodiment shown, the plug 9 is screwed on the threaded end portion I3 of the flexible conduit I. A flange I4 is provided on the conduit I inwardly of the threaded end portion l3 thereof. The shield I2 is secured in position against the flange I4 by the plug 9.

In Figure 2 of the drawings, reference character I5 designates the upper portion of a Mason jar and a conventional self-sealing cap to be applied thereto is shown at I6. When using the device, the flexible conduit I is secured by the connection B to a kettle I I, or other suitable source of steam. In making this connection, the tapered, tubular plug 9 is inserted tightly in the neck Ill. The lid I6 is then positioned on the jar I5 and raised sufficiently to permit the insertion therebeneath of the nozzle 3 and the thermometer 6. This is shown to advantage in Figure 2 of the drawing. A disc I! of Wood or other suitable material, having mounted thereon a handle I8, may be used to facilitate holding the lid I6 in position with the nozzle 3 therebeneath. With the nozzle 3 thus inserted beneath the lid I6, steam is discharged downwardly through the openings 4 for expelling the air and sterilizing the upper portion of the jar, the lid and the contents. The tem'- perature may be ascertained by consulting the thermometer B. The nozzle 3 is held under the lid I6 for a predetermined length of time and then withdrawn. The lid I6 is then pressed into position on the jar I5 where it is held by suction.

It is believed that the many advantages of a Mason jar sealing device constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of said device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

In a device of the character described, an elongated wedge-shaped steam discharge nozzle, a tubular neck on the inner end of said nozzle, an elongated handle mounted near one end on and extending laterally from said neck, a flexible steam conduit coupled at one end to said neck, and means to connect the other end of said conduit to the spout of a kettle, said other end of the conduit being externally threaded and provided with an external flange, said means including a tapered plug insertable in the kettle spout and having a threaded socket in its larger end into which the threaded end of the conduit is screwed, and a cup-shaped shield having an apertured wall spout.
